Alex Mack had a strong season and went to the Pro Bowl.
Nobody knows where Mack will play in 2014. He was drafted by the Browns and has known nothing but losing and change since he joined the team. It only seems logical that he will test the free agent market.
There are glaring needs at guard, where the Browns have John Greco and Jason Pinkston but hardly seem committed to either (even though they signed Greco to a contract extension a year ago). Lauvao did not have a good season, but it seems like he could be a better player than he’s shown. Regardless, he’ll do it with another team as the Browns probably will not bring him back.
